Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrician plier is provided with a structure with various crimping sizes, then the applicability is improved, but the operation complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the crimping size adjustable through rotation of the head. The head can be rotated to different angles (0°, 60°, 120°, 180°, 240°, 300°) to change the crimping size, transforming a static tool into a dynamic one that adapts to different crimping requirements. This resolves the contradiction by providing multiple crimping sizes without requiring multiple separate tools or complex adjustment mechanisms.
Solution Approach 2:
The patent changes the parameter of crimping size by rotating the head to different angular positions. Each rotation angle corresponds to a specific crimping size, allowing the user to select the appropriate size by simply rotating the head. This parameter change approach enables the tool to handle various crimping applications while maintaining simple operation.
2Adaptability or versatility
If the electrician plier is provided with a structure with various crimping sizes, then the applicability is improved, but the ease of operation deteriorates
Solution Approach 1:
The head is designed to be rotatable, allowing dynamic adjustment between different crimping sizes. The user can easily switch between 0°, 60°, 120°, 180°, 240°, and 300° positions by simply rotating the head, making the tool adaptable to various applications while maintaining ease of operation.
Solution Approach 2:
The crimping teeth on the head are segmented into different groups that correspond to different crimping sizes. By rotating the head to specific angles, different segments of crimping teeth are engaged, allowing the user to select the appropriate crimping size for different terminal types without complex adjustments.
3Adaptability or versatility
If the crimping size adjustment mechanism is added, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The head serves multiple functions: it can be rotated to different angles to provide various crimping sizes, and it maintains structural simplicity. This multi-functionality allows a single head design to handle multiple crimping applications without requiring separate heads or complex adjustment mechanisms for each size.
Solution Approach 2:
The head's rotatable design provides a simple dynamic adjustment mechanism. Instead of requiring separate adjustment components for each crimping size, the entire head can be rotated to achieve size changes, reducing structural complexity while maintaining versatility.
